Richardson Electronics to Distribute Broadcast Amplifier
LaFox, IL — Richardson Electronics is now distributing the RES-INGENIUM FM550-108, a new high-performance pallet amplifier made in Italy and designed for FM and HDFM radio broadcast. This Class B amplifier will deliver 500-600 watts CW output power, up to 82 percent collector efficiency, and very good harmonic suppression (-30dBc).
The rugged and reliable amplifier, using the MRF6V2300NBR1 LDMOS transistor from Freescale
Semiconductor, operates from -10 to +60°C. The typical gain (21dB) allows the system designer to supply only 4.5W input power (at 550W Pout), eliminating one or more gain stages to save cost. The FM550-108 is suitable for FM transmitter, transposer, and broadcast exciter designs.
Connectorized versions are available on request.
